Description

 TECHNICAL FIELD The present invention relates to an empty container volume reduction collection machine that crushes empty resin containers such as plastic bottles, aluminum cans, steel cans, and the like that are used for selling soft drinks, and stores the reduced volume. Is.

 Plastic containers such as plastic bottles and empty containers such as aluminum cans and steel cans are subject to recycling, and it is often seen that empty container collection boxes are installed beside vending machines such as soft drinks It is done.

 However, the installation of the empty container collection box alone has a disadvantage that the volume of the accommodated empty container is large and the transportation cost is high for processing. Conventionally, there have been devices for crushing empty containers such as aluminum cans and steel cans to reduce the capacity, but all of them are large and expensive, and their installation locations are limited.

 Here, since the resin container is lightweight and flexible, it does not break like glass even when dropped, and has excellent chemical resistance, it is widely used as a soft drink container. On the other hand, when recycling this product, due to the above flexibility, it was difficult to crush smoothly, and the volume reduction rate could not be expected much. This tendency is prominent in resin containers discarded with the lid sealed.

As patent document 1 which copes with this, the technical idea disclosed by Unexamined-Japanese-Patent No. 2001-121296 is well-known. In Patent Document 1, an elastic material that can be deformed when the relative strength with the empty resin container is weak is applied to at least the surface of the compression roller, and a plurality of spike pins are implanted on the peripheral surface of at least one roller body. A technique is shown in which compression is performed while the empty resin container is perforated with this spike pin, so as to reliably compress the empty resin container while suppressing the restoration property.
JP2001-121296 (2nd to 3rd pages)

 By the way, in the above-mentioned thing, when the empty container as an object to be processed is an empty resin container, the resilience associated with the crushing is proper. There was a problem that it was difficult to crush and the volume reduction rate could not be so high. Further, in the case where the compression is performed while the empty resin container is perforated by the spike pin, the function is to the extent that the compressed air in the empty resin container is released, and there is almost no function to suppress the recoverability.

 In addition, when the empty container as the object to be processed is an empty can, there is not much resilience associated with crushing, but the lid part and the bottom part are not easily crushed completely. In the process of storing the empty cans, there was a problem that it was difficult to harden a number of crushed empty cans into a block shape with a press.

 Therefore, the present invention has been made to solve such a problem, and reduces the volume of the empty container as the object to be processed while reducing the volume by crushing, and after various kinds of container sizes and empty containers are accommodated. An object of the present invention is to provide an empty container volume reduction collection machine that can handle the above-mentioned processing.

 The compression roller of the empty container volumetric recovery machine according to claim 1 is supported by a rotating shaft, the opposing compression rollers have a substantially symmetrical shape, and each of the compression rollers is sent from above. A receiving portion for receiving an end portion of the empty container, a hook portion for hooking a side body portion of the empty container and guiding it in a processing progress direction, and a pressing portion directly responsible for a pressing action for crushing the empty container. By the compression roller, the side barrel of the empty container is crushed and volume-reduced so that at least one end surface of the empty container is bent.

Here, the plate-like roller element made of a steel-equivalent strength means metal, ceramic, reinforced plastic, or the like. Moreover, the substantially symmetrical shape of the opposing compression rollers does not mean an exact symmetry, but means that there is no significant difference between the two due to the stacking of flat roller elements. And at least one end surface of the empty container is curved means that the empty resin container of the empty container is in a predetermined curved state on the bottom surface and the empty can is on the lid surface or the bottom surface. And about an empty can, it means that at least any one should just be in a curved state. Of course, for the empty can, it is desirable that the surface of the lid and the surface of the bottom be in a predetermined curved state.
In addition, a perforation protrusion for perforating the empty container is provided on both of the opposing compression rollers or on one or more of the roller elements.
Here, both or one of the opposing compression rollers means that it is only necessary to provide a perforation projection for forming perforations in the empty container on one or more of the roller elements.
And the said perforation protrusion part is formed in the front-end | tip part or terminal part which starts the press action of the said press part of the said roller element.
Forming at the front end portion or the end portion of the roller element to start the pressing action of the pressing element is that when the side body portion of the empty container is crushed so that at least one end surface of the empty container is bent, the hysteresis is reduced. It is easy to remain and applies a large tension.
Further, the compression roller is provided with a gap between the roller elements adjacent to each other in the axial direction of the rotation shaft.
This gap avoids an overload applied to the compression roller in units of the roller elements, and may be a distance that can be easily deformed to the extent that hysteresis does not remain.
In addition, an inclined charging chute that guides the empty container to the opposing compression roller is provided on the supply side of the empty container with respect to the opposing compression roller, and the lower side of the inclined side surface of the charging chute, the supply side from the supply side One or more elastic members stretched toward the compression roller side are disposed, and the elasticity of the elastic member leads the empty container having a predetermined weight or less to the compression roller side and exceeds the predetermined weight. Is set so that the elastic member bends and falls off the charging chute.
Here, the one or more elastic members stretched from the supply side toward the compression roller side are usually coil springs, but may be any elastic member such as synthetic rubber that can be stretched. Moreover, the elasticity should just have the function which can be selected so that the thing below a predetermined weight may be led to the compression roller side, and the thing exceeding a predetermined weight may be bent and it may remove | deviate from the said injection | throwing chute and fall.

The compression roller of the empty container volume reduction and recovery machine according to claim 2 is installed to face each other to constitute a roller unit, and one or more other roller units are provided in the subsequent stage or the preceding stage. That is, two or more pairs of opposing compression rollers are arranged.

The elastic member of the empty container volume reduction and recovery machine according to claim 3 , wherein there are two or more elastic members, their adjacent interval is made narrower than the width of the empty container for volume reduction purpose, and empty containers other than for the purpose of volume reduction. This is a wider setting.
Here, there is a function capable of selecting two or more elastic members, and those having a predetermined weight or less are led to the compression roller side at an interval between them, and those exceeding the predetermined weight are bent so as to be detached from the charging chute and fall. It only has to have.

The empty container of the empty container volume reduction collection machine according to claim 4 is an empty resin container such as a plastic bottle or an empty can such as a steel can or an aluminum can.

In the empty container volume reduction and recovery machine according to the first aspect, since the compression roller is made of a steel equivalent material, the empty container as the object to be processed is surely crushed even if there is a hard part of the lid such as a drinking mouth. The restorability after this can be lowered. Furthermore, with the bottom portion of the empty container being received in the receiving portion, the empty container is pulled down while being gripped by the hook portion, and crushing is started at the press portion from the side body portion of the empty container that is most easily crushed. The volume is reduced. Furthermore, since the hook portion that hooks the side body portion of the empty container and leads it in the processing progress direction is applied with a large crushing force so that at least one end surface of the empty container is bent, the empty container has an elastic limit. Since the deformation exceeds that, the restorability is low and it is difficult to return to the original. And since at least one end surface of the empty container is bent, even when many crushed empty cans are hardened in a block shape by a press machine in the process after storage, the direction of bending and overlapping is determined. Therefore, overlapping joints can be formed and integrated.
Further, since the perforation protrusions for perforating the empty container are provided on both of the opposing compression rollers or one or more of the roller elements , at least one end surface of the empty container is bent, Although the deformation is larger than the elastic limit, the perforation protrusion further deforms larger than the elastic limit of the empty container, and a hole is drilled in the empty container by the perforation protrusion. Therefore, the restoring force is weakened, and the reduced empty container is difficult to return.
And since the said perforation | projection protrusion part is formed in the front-end | tip part or termination | terminus part which starts the press action of the said press part of the said roller element, the side of the said empty container is bent so that the end surface of the said empty container may bend When the body part is crushed, perforation is made at an optimal position where the hysteresis of the empty container tends to remain.
Further, since a gap is provided between the roller elements adjacent to each other in the axial length direction of the rotating shaft, the gap adjacent in the axial length direction of the rotating shaft of the roller element acts as play. Even if a strong force is applied due to unexpected insertion of foreign matter, this force can be easily released, and the load on the roller element is reduced.
In addition, an inclined charging chute that guides the empty container to the opposing compression roller is provided on the supply side of the empty container with respect to the opposing compression roller, and the lower side of the inclined side surface of the charging chute, the supply side from the supply side One or more elastic members stretched toward the compression roller side are disposed, and the elasticity of the elastic member leads the empty container having a predetermined weight or less to the compression roller side and exceeds the predetermined weight. Is set so that the elastic member bends and falls off the charging chute. Therefore, the desired empty container is guided to the compression roller side by the elastic member, and other heavy containers are dropped without being guided to the compression roller by bending the elastic member to widen the interval. For this reason, for example, even if heavy empty bottles are thrown in, the gap between the elastic members is not extended and guided to the compression roller, so that scattering of the glass pieces due to crushing and occurrence of an abnormality in the mechanism including the compression roller occur. Prevented in advance.

Since the empty container volumetric recovery machine according to claim 2 is provided so that there are a plurality of roller units installed so that the compression rollers face each other, in addition to the effect of claim 1, By being repeatedly crushed, the restoration property can be suppressed, and volume reduction is ensured.

The empty container volume reduction and recovery machine according to claim 3 , wherein the elastic member has two or more elastic members, an interval between them is narrower than a width of the empty container for volume reduction purpose, and an empty container outside the volume reduction purpose. since those set wider than class, in addition to the effects of claim 1, desired air container is reliably guided to the compression roller through the elastic member input chute. On the other hand, containers narrower than a predetermined width of a desired empty container are dropped as they are without being guided to the compression roller because the interval between the elastic members is wider. For this reason, for example, even when narrow empty bottles are inserted, the elastic members do not pass through the gap between the elastic members and are not guided to the compression roller. Is prevented in advance.

Since the empty container volume reduction collection machine concerning Claim 4 uses an empty resin container or an empty can as an empty container as a processed object, the effect given in any 1 paragraph of Claims 1 thru / or 3 In addition, the empty resin container is crushed and reduced in volume as much as possible including the lid and drinking mouth, and the empty can is crushed only on the side barrel without crushing the lid and / or bottom of both ends. The volume will be reduced.

Next, embodiments of the present invention will be described with reference to the drawings.

 A closing chute shutter 25 is provided near the end of the closing chute 24. The closing chute shutter 25 has a flat plate shape and is configured to operate in conjunction with the closing door 23. When the closing door 23 is opened, the terminal portion of the closing chute 24 is closed and the hand inserted by mistake. Etc. are prevented from reaching the press unit 3. Specifically, the closing chute shutter 25 is slidably disposed near the end of the closing chute 24, and the closing door 23 and the closing chute shutter 25 are linked via a link mechanism 26. FIG. When the closing door 23 is opened, the closing chute shutter 25 is closed. As shown by a solid line in FIG. 2, when the closing door 23 is closed, the closing chute shutter 25 is opened.

 The press unit 3 is fixed by the support frame 4 above the storage box 2 so as to be positioned below the charging chute 24. The press unit 3 includes an upper roller unit 5 that first presses the empty resin container A that is input from the input chute 24, and draws the empty resin container A that is primarily pressed by the roller unit 5 downward. It comprises a lower roller unit 6 that performs the next press, and a common drive motor 7 that drives them.

 The roller unit 5 at the top of the press unit 3 has a first compression roller 51A and a second compression roller 51B driven by a drive motor 7 as central members. The first compression roller 51A and the second compression roller 51B driven by the drive motor 7 may transmit rotation from the first compression roller 51A to the second compression roller 51B.

 In the following description, when the upper roller unit 5 and the lower roller unit 6 are not particularly limited and which compression roller is described, they are simply referred to as “compression roller R”.

 As shown in FIG. 5, the first compression roller 51A and the second compression roller 51B are rotatable with respect to the support frame 4 fixed above the storage box 2 so as to face each other by rotating shafts 52A and 52B. It is supported by. In addition, gears 53A and 53B are fixed to shaft ends of the respective rotation shafts 52A and 52B. Then, the drive gear 7a of the drive motor 7 and the gear 53A of the first compression roller 51A are meshed, and the gears 53A and 53B of the first compression roller 51A and the second compression roller 51B are meshed with the first compression roller 51A. The second compression roller 51B rotates in the reverse direction.

 Next, specific configurations of the first compression roller 51A and the second compression roller 51B will be described.

 Each of the first compression roller 51A and the second compression roller 51B is composed of a plurality of steel plate-like roller elements Rp divided into pieces, and these are supported by rotating shafts 52A and 52B, respectively. The first compression roller 51A and the second compression roller 51B arranged opposite to each other are substantially symmetrical, and each compression roller R is sent from above and a press portion P that directly bears the crushing action. In addition, it has a receiving portion C that receives the bottom of the empty resin container A, and a hook portion F that hooks the empty resin container A and guides it in the processing progress direction. The roller element Rp can be appropriately configured using other metals made of steel, other metals having a strength equivalent to steel, ceramics, reinforced plastics, and the like.

 As shown in FIG. 4 (b), the roller element Rp constituting the compression roller R is shown in FIG. 4 (a) and a roller element Rp2 with a perforated protrusion Pa for perforating the empty resin container A. As described above, the roller element Rp2 includes the press part P that does not have the perforated projection part Pa, the roller part Rp1 that includes only the receiving part C and the hook part F. In the second compression roller 51B shown in FIG. 3, four roller elements Rp2 each having a perforation protrusion Pa are arranged, and in the first compression roller 51A, a roller having four perforation protrusions Pa of the second compression roller 51B. A roller element Rp2 having two perforated protrusions Pa is disposed so as to be positioned approximately in the middle of the element Rp2. Of course, since the roller element Rp is a divided body, the number and positions of the roller elements Rp2 having the perforated protrusions Pa can be easily changed according to the size of the empty resin container A to be reduced.

 Further, as shown in the enlarged view of FIG. 3, a slight play gap S is provided between the adjacent roller elements Rp, and a strong force is applied from the empty resin container A or the erroneously introduced foreign material side. In such a case, the force is easily released by the play gap S of the roller element Rp, and the load applied to the press unit 3 of the empty container volumetric recovery machine 1 is reduced.

 On the other hand, the lower roller unit 6 is generally applied in the same shape as the upper roller unit 5, and includes a first compression roller 61A and a second compression roller made of a plurality of steel plate-like roller elements Rp. 61B, and are rotatably supported so as to be opposed to and aligned with the support frame 4 by rotating shafts 62A and 62B, respectively. Further, gears 63A and 63B are fixed to the shaft ends of the rotating shafts 62A and 62B, and the drive gear 7a of the drive motor 7 and the gear 63A of the first compression roller 61A are engaged with each other, and the first compression roller 61A and The gears 63A and 63B of the second compression roller 61B are meshed with each other.

 In addition, since the empty resin container A is crushed in advance by the upper roller unit 5, the compression roller R of the roller unit 6 is made up of a plurality of steel plate-like roller elements Rp as described above. In addition to the configuration, it is also possible to configure the synthetic rubber or other elastic material integrally formed as shown in FIG.

 The distance between the upper roller unit 5 and the lower roller unit 6 is set to be relatively narrow, and the empty resin container A sent from the upper roller unit 5 is easily pulled in by the lower roller unit 6. ing.

 As shown in FIG. 8, the upper roller unit 5 and the lower roller unit 6 have the same posture positions of the first compression rollers 51A and 61A and the second compression rollers 51B and 61B, respectively. When the five press portions P are close to each other, the press portions P of the lower roller unit 6 are also close to each other.

 As shown in FIG. 6, the distance L1 between the receiving portions C when the receiving portions C of the compression roller R face each other is 50 to 80% with respect to the inter-axis distance L2 of the rotation shaft of the compression roller R. ] It is set as follows. That is, by adopting a configuration in which the portion of the receiving portion C of the compression roller R is thus narrowed, the diameter of each compression roller R is reduced, and the distance L2 between the axes of each compression roller R is reduced, so that the press unit 3 While achieving the overall miniaturization, the empty resin container A can be accepted.

 Incidentally, regarding the above-described empty container volumetric recovery machine 1, in this embodiment, when detailed numerical data is given, the drive motor 7 can obtain a rated torque output of about 550 [kgf · cm] at the compression roller R. An electric motor is used. The drive motor 7 uses an electric motor that can be rotated forward and backward as an example. For example, when the compression roller R stops due to a foreign object that cannot be crushed, the compression roller R is reversed and pinched. A reversing switch 8 is provided that enables an operation to take out foreign matter or the like to the opposite (upward) side. As shown in FIG. 1, the reversing switch 8 is disposed at the upper front portion of the storage box 2 where the front door 20 is opened.

 Further, the roller element Rp has a diameter D of about 75 [mm] excluding the perforated protrusions Pa, an arc length N of the press part P of about 45 [mm], and a thickness of about 4.5 [mm]. mm] (see FIG. 4A). The length N of the arc of the press part P can be variously changed according to the standard of the empty resin container A, and is selected according to the processing target.

 Next, referring to FIG. 8 to FIG. 10 showing the operation of the upper roller unit 5 and the lower roller unit 6 of the empty container volume reduction and recovery machine 1 of the present embodiment, the above-mentioned FIG. 1 to FIG. 6 and FIG. The operation will be described with reference to FIG.

 FIG. 7 is an explanatory diagram showing the difference in action of the elastic member of the charging chute of FIG. 1 on the empty resin container or empty bottles, and in particular, the action of the elastic member 24a of the charging chute 24 on the empty resin container A or empty bottles B. It is explanatory drawing which shows the difference.

 FIG. 8 is an explanatory view showing the operation of the press unit before the primary press for the empty resin container by the empty container volume reducing and collecting machine according to the first embodiment of the present invention, and FIG. 9 is the press at the time of the primary press following FIG. 10 is an explanatory diagram showing the operation of the unit, FIG. 10 is an explanatory diagram showing the operation of the press unit at the time of the secondary press following FIG. 9, and FIG. 11 is a press unit in the empty container volumetric recovery machine according to the first embodiment of the present invention. FIG. 12 is a partial cross-sectional view showing a modification of the press unit in the internal structure of the empty container volume recovery machine according to the first embodiment of the present invention, and FIG. 13 is a perspective view showing a modification of the lower roller unit. FIG. 14 is a plan view showing a modification of the press portion of the compression roller constituting the press unit 3 in the internal structure of the empty container volume reducing and collecting machine according to the first embodiment of the present invention, and FIG. 14 shows the empty according to the first embodiment of the present invention. Yong The container in the internal structure of the compacting harvester is a partial perspective view showing a modified example where to separating the air resin container and empty bottles.

Input (see Fig. 1, Fig. 2, Fig. 7)
First, the drive motor 7 is started by turning on the switch. Thereby, the rotation of the drive gear 7a of the drive motor 7 is transmitted to the first compression rollers 51A and 61A of the upper roller unit 5 and the lower roller unit 6, and the rotation of the drive gear 7a of the drive motor 7 is The gears 53B and 63B are transmitted to the second compression rollers 51B and 61B, respectively.

 Thus, in the state where the empty container volumetric recovery machine 1 is driven, the empty resin container A with the lid Aa is opened with the upper charging door 23 opened in the vertical posture. At this time, when the closing door 23 is opened, the closing chute shutter 25 provided in the vicinity of the closing end of the closing chute 24 is closed as shown by a two-dot chain line in FIG. And the like are prevented from being caught in the press unit 3 in advance. When the closing door 23 is closed, the closing chute shutter 25 is opened, and the empty resin container A stopped on the closing chute shutter 25 is dropped by its own weight to the lower press unit 3 side.

 When the empty resin container A is inserted with the charging door 23 opened, the empty resin container A is light and slides down on the elastic member 24a on the side surface of the charging chute 24 (see FIG. 7A). Is done. On the other hand, for example, in the case of empty bottles B such as juices and nutritional drinks that are heavier than the empty resin container A, the elastic member 24a is bent as shown in FIG. As shown in c), the empty bottles B are dropped downward before reaching the press unit 3 by passing through between the elastic members 24a. Therefore, the glass pieces of the empty bottles B crushed by the press unit 3 are not scattered in the container 21, and naturally, it is not necessary to remove the glass pieces. Further, since the empty bottles B are not accidentally pressed, it is possible to prevent the press unit 3 from being abnormal.

Primary press (see Figs. 8 and 9)
As shown in FIG. 8, after the empty resin container A reaches the upper roller unit 5 and is received by the receiving portion C of the compression roller R, as shown in FIGS. 9 (a) and 9 (b). The crushing is started from the side body Ab of the empty resin container A that is pulled down while being held by the hook part F and is most easily crushed by the press part P. At this time, the volume of the side body Ab of the empty resin container A is reduced to such an extent that one end surface of the empty resin container A is bent while being held by the hook part F. The tension exceeding the elastic limit is applied to the empty resin container A, and the empty resin container A is deformed exceeding the elastic limit, and the restoring property is lowered. For this reason, the compression proceeds smoothly, and the perforation protrusion Pa acts on the empty resin container A at the end of the press operation by the press part P, and the perforation H is made. Since the drilling operation is performed at such timing, the drilling operation is smooth, and the empty resin container A is not caught on the drilling projection portion Pa. In particular, as shown in FIG. 15, when the side barrel Ab of the empty resin container A is crushed to such an extent that one end surface of the empty resin container A is bent, the hysteresis in accordance with the empty resin container A tends to remain at an optimal position. Perforations H are applied.

 That is, since the one end surface consisting of the bottom part Ac of the empty resin container A is bent while being held by the hook part F, the volume is reduced by crushing while applying tension to the side body part Ab of the empty resin container A. A tension exceeding the elastic limit is applied in the vicinity gripped by the hook portion F, and the empty resin container A becomes a deformation region H0 where the elastic limit is exceeded and the hysteresis remains, and the restoring property is lowered, so that it is difficult to return to the original state. Further, when the perforation protrusion Pa acts on the empty resin container A at the beginning of the pressing operation and the perforation H is made, the side barrel of the empty resin container A is bent to the extent that one end surface of the bottom portion Ac of the empty resin container A is bent. When the portion Ab is crushed, the perforation H is provided at an optimal position where the hysteresis corresponding to the empty resin container A tends to remain. However, the perforation vicinity region H1 around the perforation H undergoes elastic deformation in which the hysteresis tends to remain, so that the restoration property is low and it is difficult to return to the original state.

 Here, the timing of the punching protrusion Pa is such that the punching protrusion Pa acts on the empty resin container A at the start of the press operation by the press part P or finally, and a large tension is applied, and the punching H is made there. If set, in particular, the stress that tends to return to the restored state from the bent end surface of the bottom portion Ac of the empty resin container A becomes weaker and the recoverability becomes lower.

 At this time, when a strong force is applied to the upper roller unit 5 from the empty resin container A or a foreign matter put in error, this force is easily released by the gap S of the roller element Rp. The load applied to the press unit 3 portion of the empty container volume reduction collection machine 1 is reduced.

Secondary press (see FIGS. 10 (a) and 10 (b))
The empty resin container A that is pressed and punched by the upper roller unit 5 subsequently reaches the lower roller unit 6 and is received by the receiving portion C of the compression roller R, and immediately by the hook portion F. It is sandwiched and drawn between the first compression roller 61A and the second compression roller 61B. The empty resin container A drawn between the first compression roller 61 </ b> A and the second compression roller 61 </ b> B is pressed again by the press part P and is punched by the punching projection part Pa at the pressing action terminal part of the press part P. Since a gap S similar to that of the upper roller unit 5 is provided between the roller elements Rp constituting the lower roller unit 6, the lower roller unit can be formed from the empty resin container A or a foreign matter put in error. Even when a strong force is applied to 6, this force is easily released, and the load applied to the press unit 3 portion of the empty container volume reduction collection machine 1 is reduced.

After secondary press (see Fig. 1)
The empty resin container A that has been subjected to the secondary press in the press unit 3 is dropped by its own weight and is accommodated in the accommodation bag 22 attached to the accommodation device 21 of the accommodation box 2. Since the empty resin container A is crushed in the storage bag 22 of the container 21, a very large number of empty resin containers A can be stored as compared with a case where the empty resin container A is not crushed at all. The empty resin container A perforated by the perforated protrusions Pa is deformed to exceed the elastic limit, so that the restorability is low, and this tendency is remarkable compared to the empty resin container A not perforated by the perforated protrusions Pa. It is.

 Further, unlike the prior art, it is not simply deformed by pressing force, but an external force partially applied to the empty resin container A is applied and its hysteresis is easily retained, so that it is more resilient than the conventional one. Is difficult to return to the original shape.

 Since the compression roller R is composed of a plurality of divided roller elements Rp, the number and position of the roller elements Rp having the perforated protrusions Pa are adapted to the size of the empty resin container A that is the processing target. It can be changed as appropriate.

 Next, as a modified example of the internal structure of the empty container volumetric recovery machine 1 of the present embodiment, refer to the partial cross-sectional view of FIG. I will explain.

 In FIG. 12, the empty resin container A reaching the end of the charging chute 24 is detected by the charging detection switch 9 using a counter-transmission type infrared sensor and the like, and the drive motor 7 is automatically driven. The completion of the discharge of the container A is detected by a similar compression end detection switch 10, and the drive of the drive motor 7 is automatically stopped at a specific time limit.

 That is, when the empty resin container A is inserted, an ON signal is output from the insertion detection switch 9 and the drive motor 7 is driven. When the empty resin container A is detected, the compression end detection switch 10 outputs an ON signal, and when the empty resin container A is detected to be dropped from the press unit 3, the compression end detection switch 10 is turned off. Is output at the time when the OFF signal is output. In addition, when the empty resin container A stops on the way, the reverse rotation switch 8 can be operated and the compression roller R can be reversed and taken out.

 In addition, assuming an abnormal situation in which an incompressible object such as a stone or an iron lump is inserted and the drive of the drive motor 7 is stopped, an overcurrent exceeding the current value during normal operation flows to the drive motor 7. In this case, it is desirable to provide an overcurrent prevention circuit that can stop the current to the drive motor 7.

 As a modified example of the internal structure of the empty container volumetric recovery machine 1 of the present embodiment, in the plan view of FIG. 13, the non-slip teeth are applied to the press portion P of the compression roller R constituting the press unit 3. Pb is provided. Since the pressure applied to the empty resin container A by the non-slip teeth Pb becomes a deformation exceeding the elastic limit, the restoring property is lowered.

 FIG. 14 is a partial perspective view showing a modified example in which the container in the internal structure of the empty container volume reduction collection machine according to the first embodiment of the present invention is installed so as to separate the empty resin container and the empty bottles.

 As a modified example of the internal structure of the empty container volume recovery machine 1 of the present embodiment, in the partial perspective view of FIG. 14, the container 21 shown in FIG. 21A and a container 21B that accommodates empty bottles B are installed separately.

 FIG. 15 is a perspective view showing a modification in which a recovery mechanism for storing drinking water or the like is additionally provided in the storage box in the internal structure of the empty container volume reduction recovery machine according to the first embodiment of the present invention. Furthermore, as a modified example of the internal structure of the empty container volume reduction collection machine 1 of the present embodiment, in the perspective view of FIG. 15, there is provided a collection mechanism for containing the drinking water remaining in the resin container in the storage box 2. It is added. Specifically, a drinking water inlet 27 is provided above the storage box 2, and the beverage is installed side by side in the storage container 21 from the drinking water inlet 27 through the relay pipe 28 in the storage box 2. It is connected to a water tank 29.

Embodiment 2
In the first embodiment, the empty resin container A has been described. However, the empty can K can be similarly processed. A common configuration is omitted, and only the operation is briefly described.

 FIG. 17 is an explanatory view showing the operation of the press unit at the time of primary press showing the operation of the main part of the second embodiment of the present invention. FIG. 18 is an explanatory view showing the operation of the press unit during the secondary press following FIG.

Primary press (see Fig. 17)
As shown in FIG. 17, after the empty resin container A reaches the upper roller unit 5 and is received by the receiving portion C of the compression roller R, as shown in FIGS. 17 (a) and 17 (b). Crushing is started from the side barrel Ab of the empty can K made of steel or aluminum, which is pulled down while being held by the hook portion F while being tensioned and is most easily crushed by the press portion P.

 At this time, the side barrel of the empty can K is applied while applying tension to the side barrel Ab of the empty can K so that one end surface of the bottom Ac or the lid Ad of the empty can K is bent while being held by the hook portion F. Since the portion Ab is crushed and reduced in volume, a force exceeding the elastic limit is applied near the portion gripped by the hook portion F, and the empty can K is deformed beyond the elastic limit, its hysteresis remains, and the restorability Will not return to its original shape. For this reason, the compression proceeds smoothly, and the punching protrusion Pa acts on the empty can K at the end of the pressing operation by the press part P, so that the punching is performed. Since the drilling operation is performed at such timing, the drilling operation is smooth, and the empty can K is not caught on the drilling protrusion Pa. In particular, when the side barrel Ab of the empty can K is crushed to such an extent that one end surface of the bottom portion Ac or the lid portion Ad of the empty can K is bent, the hysteresis in accordance with the empty can K tends to remain at the optimum position. Is given. Of course, only the contents may be discharged.

 That is, the outer body K of the empty can K is applied with an external force to the extent that one end surface of the illustrated bottom portion Ac of the empty can K is bent while being gripped by the hook portion F. A force exceeding the elastic limit is applied in the vicinity gripped by the hook portion F, and the empty can K becomes a deformation region H0 in which hysteresis exceeding the elastic limit remains, and the recoverability becomes low. Further, when the punching protrusion Pa acts on the empty can K at the beginning of the pressing operation and the punching H is made, the side barrel Ab of the empty can K is bent to such an extent that one end surface composed of the bottom Ac of the empty can K is bent. When crushing, the perforation H is provided at an optimal position where the hysteresis corresponding to the empty can K tends to remain. However, the perforation vicinity region H1 around the perforation H is elastically deformed so that the hysteresis tends to remain.

 Here, when the punching protrusion Pa is set such that the punching protrusion Pa acts on the empty can K at the start of the press operation by the press part P or finally, the bottom of the empty can K is set. Since the stress that causes the end surface of Ac to bend from the bent state to the restored state is weakened and the restoring property is lowered, it is difficult to return to the original state.

Secondary press (see FIGS. 18 (a) and 18 (b))
The empty can K that has been pressed and punched by the upper roller unit 5 subsequently reaches the lower roller unit 6 and is received by the receiving portion C of the compression roller R, and immediately sandwiched by the hook portion F. The first compression roller 61A and the second compression roller 61B are pulled in. The empty can K drawn between the first compression roller 61 </ b> A and the second compression roller 61 </ b> B is pressed again by the press part P and is punched by the punching protrusion Pa at the end of the pressing action of the press part P.

After secondary press (see Fig. 1)
The empty can K that has been subjected to the secondary press in the press unit 3 is dropped by its own weight and accommodated in the accommodation bag 22 attached to the accommodation device 21 of the accommodation box 2. Since the empty can K is crushed in the storage bag 22 of the container 21, a very large number of empty cans K can be stored as compared with a case where the empty can K is not crushed at all. And since the empty can K pierced by the piercing projection Pa is deformed beyond the elastic limit, its hysteresis has a low restoration property, and this tendency is compared with the empty can K not pierced by the piercing projection Pa. It is remarkable.

 Since the compression roller R is composed of a plurality of divided roller elements Rp, the number and position of the roller elements Rp having the perforated protrusions Pa are appropriately adjusted so as to match the size of the empty can K that is the object to be processed. It is possible to change.

 In particular, the perforated protrusion Pa can be provided on either the upper roller unit 5 or the lower roller unit 6 in the press unit 3. Of course, the perforation protrusion Pa can be provided on both the upper roller unit 5 and the lower roller unit 6 in the press unit 3. At this time, it is desirable not to have the same perforation H.

 In the present embodiment, an empty container volume recovery machine 1 that holds an empty container such as an empty resin container A or an empty can as an object to be processed is sandwiched between opposing compression rollers and reduced in volume and stored. Is constituted by being pivotally supported on the rotation shafts 52A, 52B, 62A, 62B in a state where a plurality of flat roller elements Rp (Rp1, Rp2) made of a steel equivalent strength material are overlapped, The opposing compression rollers R have a substantially symmetrical shape, and each of the compression rollers R receives the end of an empty container such as the empty resin container A or empty can K sent from above, and the empty section A hook portion F that hooks the side body Ab of the container and guides it in the direction of processing; and a press portion P that directly bears the pressing action of crushing the empty container, and at least the empty resin container by the opposing compression roller R A or empty Is characterized in that one end face of the empty container K, etc. is volume reduced by crushing side barrel Ab of empty containers such as empty resin container A or cans K to curved.

 Since the compression roller R is made of steel, it can be reliably crushed even if there is a hard part of the lid, such as a spout, on an empty container such as an empty resin container A or empty can K. The restorability after this can be lowered. Further, since the compression roller R is formed by stacking a plurality of flat roller elements Rp (Rp1, Rp2) which are divided bodies, an empty resin container A or an empty can K or the like that is crushed and reduced in volume is used. The adjustment of the length in the width direction according to the container can be changed. Further, with the bottom portion of the empty container such as the empty resin container A or empty can K received in the receiving part C, the hook part F is pulled down while holding the empty container such as the empty resin container A or empty can K and pushed most. Since the crushing is started at the press part from the side body part of the empty container which is easy to be crushed, the volume can be reduced smoothly. Further, the side body Ab of the empty container such as the empty resin container A or the empty can K is bent so that at least one end surface of the bottom part Ac or the lid part Ad of the empty container such as the empty resin container A or empty can K is bent. Since the hook portion F that is hooked and guided in the processing progress direction suddenly gives a large crushing force, an empty container such as the empty resin container A or the empty can K is deformed to exceed the elastic limit, and thus the restorability is low. It becomes difficult to return to the original. And since at least one end surface consisting of the bottom part Ac or the lid part of the empty container such as the empty resin container A or the empty can K is bent, a large number of crushed empty resin containers A or Even when empty cans K such as empty cans K are hardened in a block shape by a press machine, the overlapping and overlapping directions are determined, so that overlapping joining is possible and integration is possible.

 In other words, since the compression roller R is made of a material having a strength equivalent to steel, the empty resin container A as the object to be processed can be reliably crushed even if there is a hard part of the lid Aa such as a drinking mouth. Since the pressure applied to the container A becomes a deformation exceeding the elastic limit, the restorability after this can be lowered. Further, since the compression roller R is configured by superposing flat roller elements Rp which are a plurality of divided bodies, the adjustment of the length in the width direction in accordance with the empty resin container A which is crushed and reduced in volume is changed. It is flexible and can accommodate various container sizes. Furthermore, with the bottom portion of the empty resin container A being received in the receiving portion C, the empty resin container A is pulled down while being gripped by the hook portion F, and from the side body portion Ab of the empty resin container A that is most easily crushed to the press portion P. Since crushing starts, the volume is reduced smoothly.

 Further, the compression roller R of the empty container volume reduction and recovery machine 1 of the present embodiment is provided with a perforation protrusion Pa on some of the roller elements Rp that constitute both or one of the opposing rollers, and this perforation protrusion is It is provided at the end of the press part P. For this reason, for example, even if the lid Aa is attached to the empty resin container A, the volume is smoothly reduced by the perforation.

 A slight gap S is formed between the roller elements Rp (Rp1, Rp2) of the empty container volume reduction collection machine 1 of the present embodiment and adjacent to each other in the axial direction of the rotating shafts 52A, 52B (62A, 62B). Is provided. For this reason, even if a strong force is applied from the empty resin container A or the erroneously introduced foreign material side, the force is easily released by the gap S of the roller element Rp. 3 can be reduced.

 Further, the compression roller R of the empty container volume reduction and recovery machine 1 of the present embodiment is installed to face the roller unit, and the lower roller unit 6 is provided downstream of the upper roller unit 5. . In this way, the roller unit is provided in a plurality of units with the upper roller unit 5 and the lower roller unit 6. For this reason, since the empty resin container A is repeatedly crushed, deformation exceeding the elastic limit can be achieved, so that its restoring property can be suppressed and volume reduction can be ensured.

 Furthermore, a charging chute 24 is provided in front of the compression roller R of the empty container volume reduction and recovery machine 1 of the present embodiment, and the empty resin container A is inclined and guided. The two elastic members 24a stretched from the inlet side toward the compression roller R side, and the elastic force of the elastic member 24a supports the empty resin container A having a predetermined weight or less while supporting the empty resin container A. On the other hand, the empty bottles B exceeding the predetermined weight are set so that the elastic member 24a is bent and dropped as it is. Thus, for example, even when heavy empty bottles B are inserted, the gap between the elastic members 24a is not widened and guided to the compression roller R, so that the mechanism includes the scattering of the glass pieces due to crushing and the compression roller R. Occurrence of abnormalities can be prevented in advance.

 In addition, in the empty container volume reduction and recovery machine 1 of the present embodiment, two elastic members 24a are stretched, and the gap between them is narrower than the predetermined width of the empty resin container A, and the empty bottle is narrower than the predetermined width. It is set wider than the class B. For this reason, the empty bottles B can pass through as they are without increasing the interval between the elastic members 24a. Thereby, even if empty bottles B having a narrower width than the empty resin container A are inserted, the gap between the elastic members 24a is not guided to the compression roller R, so that the glass pieces are scattered by the crushing or the compression roller R. Occurrence of an abnormality in a mechanism including the above can be prevented in advance.

 Further, the bending of the empty container by the opposing compression roller has been described with respect to one end surface of the bottom part Ac or the cover part Ad. However, when the present invention is implemented, at least two of the bottom part Ac and the cover part Ad of the empty container are used. Although it is desirable that the end face bends, even if at least one end face made of the bottom part Ac or the cover part Ad is bent, even when a large number of crushed empty cans are hardened in a block shape by a press machine , Bent and overlapped, overlapped between each other, and can be integrated.

 And although the empty container volume reduction collection machine 1 of this Embodiment was demonstrated on the assumption of empty containers, such as the empty resin container A or the empty can K, if it carries out from the main point of this invention made to stress and deform | transforms, paper Can also be used for cups. That is, as an empty container, it becomes the empty resin container A, the empty can K paper cup, etc.
